-主配置文件位于 `/opt/hubproxy/config.toml`：
+## 免责声明
-
-为了IP限流能够正常运行，反向代理需要传递IP头用来获取访客真实IP，以caddy为例：
-```
-example.com {
-    reverse_proxy 127.0.0.1:5000 {
-        header_up X-Forwarded-For {http.request.header.CF-Connecting-IP}

+title: 环境变量
+description: HubProxy 支持的环境变量说明。
+---
+
+环境变量在加载 `config.toml` 之后覆盖对应配置项。未列出的配置段（如 `[registries]`、`[tokenCache]`、`[access].whiteList`）只能通过配置文件修改。
+

+|---------|---------|------|
+| `CONFIG_PATH` | — | 配置文件路径，默认 `./config.toml` |
+| `SERVER_HOST` | `[server].host` | 监听地址 |
+| `SERVER_PORT` | `[server].port` | 监听端口 |
+| `ENABLE_H2C` | `[server].enableH2C` | 启用 HTTP/2 Cleartext（`true`/`false`） |
+| `ENABLE_FRONTEND` | `[server].enableFrontend` | 启用 Web 界面（`true`/`false`） |
+| `MAX_FILE_SIZE` | `[server].fileSize` | 单文件大小上限（字节） |
+| `RATE_LIMIT` | `[rateLimit].requestLimit` | 每 IP 每周期请求数 |

+| `IP_WHITELIST` | `[security].whiteList` | 追加限流豁免 IP，逗号分隔 |
+| `IP_BLACKLIST` | `[security].blackList` | 追加封禁 IP，逗号分隔 |
+| `ACCESS_PROXY` | `[access].proxy` | 上游 SOCKS5 代理地址 |
+| `MAX_IMAGES` | `[download].maxImages` | 批量离线镜像数量上限 |
+
+## 示例
+
+```bash
+# systemd / 本地运行
+CONFIG_PATH=/etc/hubproxy/config.toml ./hubproxy
+
+# Docker 快速调参
+docker run -d \
+  -e SERVER_PORT=5000 \

+  -v ./config.toml:/app/config.toml:ro \
+  ghcr.io/sky22333/hubproxy
+```
+
+## 使用场景
+
+| 场景 | 建议 |
+|------|------|
+| systemd 服务 | `CONFIG_PATH=/etc/hubproxy/config.toml`（服务文件已内置） |
+| Docker | 挂载 `/app/config.toml`，临时参数用 `-e` |
+| 开发调试 | `CONFIG_PATH=./src/config.toml go run .` |

+配置文件默认路径为工作目录下的 `config.toml`，可通过 `CONFIG_PATH` 环境变量覆盖。完整环境变量列表见 [环境变量](/configuration/environment/)。
+
+## [server]
+
+| 键 | 类型 | 默认值 | 说明 |
+|----|------|--------|------|
+| `host` | string | `0.0.0.0` | 监听地址 |
+| `port` | int | `5000` | 监听端口 |
+| `fileSize` | int | `2147483648` | 单文件大小上限（字节），仅影响 GitHub / Hugging Face URL 代理 |
+| `enableH2C` | bool | `false` | 启用 HTTP/2 Cleartext |
+| `enableFrontend` | bool | `true` | 启用 Web 界面（Vue SPA） |
+
+## [rateLimit]
+
+| 键 | 类型 | 默认值 | 说明 |
+|----|------|--------|------|
+| `requestLimit` | int | `500` | 每 IP 每周期允许请求数 |
+| `periodHours` | float | `3.0` | 限流周期（小时） |
+
+IPv4 按完整 IP 计数，IPv6 按 `/64` 网段计数。仅前端静态路由（`/`、`/images`、`/search`、`/favicon.ico`、`/assets/*`）不计入限流；`/ready`、API 与代理请求均会计入。
+
+:::note
+Docker 拉取一个镜像会请求多个 layer，每个 HTTP 请求均消耗限流配额。
+:::
+
+## [security]
+
+| 键 | 说明 |
+|----|------|
+| `whiteList` | 限流豁免 IP 列表（支持 CIDR，单 IP 自动补 `/32`） |
+| `blackList` | 直接拒绝访问的 IP 列表（403） |
+
+:::note
+`[security]` 黑白名单仅影响限流与 IP 封禁，**不**控制可代理的仓库。
+:::
+
+## [access]
+
+| 键 | 说明 |
+|----|------|
+| `whiteList` | 允许代理的仓库/镜像（空=不限制） |
+| `blackList` | 禁止代理的仓库/镜像 |
+| `proxy` | 上游 SOCKS5 代理，如 `socks5://127.0.0.1:1080` 或 `socks5://user:pass@host:1080` |
+
+仓库规则支持通配符，如 `owner/*`、`*/repo-name`。
+
+## [download]
+
+| 键 | 类型 | 默认值 | 说明 |
+|----|------|--------|------|
+| `maxImages` | int | `10` | 批量离线镜像数量上限 |
+
+## [registries]
+
+每个 Registry 条目：
+
+| 键 | 说明 |
+|----|------|
+| `upstream` | 上游 Registry 地址 |
+| `authHost` | 认证端点（用于匹配 token 请求） |
+| `authType` | 认证类型标识（`anonymous`/`github`/`google`/`quay`） |
+| `enabled` | 是否启用 |
+
+默认预置 `ghcr.io`、`gcr.io`、`quay.io`、`registry.k8s.io`。Docker Hub 固定走 `registry-1.docker.io`，不在此段配置。
+
+:::note
+当前版本对所有 Registry 均使用匿名拉取（`authn.Anonymous`），`authType` 仅用于标识认证端点类型，**尚未**实现 GitHub Token 或 Google 服务账号等私有仓库凭据，且不转发客户端 `Authorization` 头。**无法**通过 HubProxy 拉取需要认证的私有镜像。
+:::
+
+## [tokenCache]
+
+| 键 | 类型 | 默认值 | 说明 |
+|----|------|--------|------|
+| `enabled` | bool | `true` | 启用 Token/Manifest 缓存 |
+| `defaultTTL` | string | `"20m"` | 普通 tag 的 Manifest 默认缓存时间 |
+
+Manifest 缓存 TTL 规则：
+
+| 条件 | TTL |
+|------|-----|
+| digest（`sha256:...`） | 24 小时 |
+| `latest` / `main` / `master` / `dev` / `develop` | 10 分钟 |
+| 其他 tag | `[tokenCache].defaultTTL` |
+
+上游 token 响应中的 `expires_in` 会用于 token 缓存（预留 5 分钟安全余量，最短 5 分钟）。
+
+## HTTP 端点
+
+| 路径 | 说明 |
+|------|------|
+| `GET /ready` | 健康检查，返回 `ready`、`version`、`uptime_sec` 等（**计入** IP 限流） |

+title: 推荐部署架构
+description: 公网部署 HubProxy 的推荐拓扑与安全要求。
+---
+
+公网服务建议通过反向代理暴露 HubProxy，保障服务器安全。
+
+## 推荐拓扑
+
+```
+用户 → CDN（可选）→ Caddy/Nginx（私网/本机）→ HubProxy:5000
+```
+
+| 组件 | 作用 |
+|------|------|
+| CDN | 可选，提供 TLS 与边缘加速 |
+| 反向代理 | 终止 TLS、写入真实客户端 IP、隐藏后端端口 |
+| HubProxy | 处理 Docker/GitHub 代理逻辑 |
+
+## 反代部署时的要求
+
+若采用上文推荐拓扑（用户 → 反代 → HubProxy），需满足：
+
+1. **反代覆盖写** `X-Forwarded-For` / `X-Real-IP`（防止用户伪造 IP，勿 append 客户端自带头）
+2. **建议 5000 仅对反代可达**（绑定 `127.0.0.1` 或防火墙限制）
+3. 反代覆盖写 `X-Forwarded-Host`（防止 `.sh` 脚本 Host 注入）
+
+## 各场景对照
+
+| 部署方式 | 每用户独立限流 | IP 防伪造 | 推荐度 |

+
+## Caddy
+
+### 基础反代
+
+```txt
+example.com {
+    reverse_proxy 127.0.0.1:5000 {
+        header_up X-Real-IP {remote}

+
+:::caution
+避免使用 `proxy_add_x_forwarded_for`，它会 append 客户端自带的 `X-Forwarded-For`，可能导致 IP 解析错误。
+:::
+
+```nginx
+location / {
+    proxy_pass http://127.0.0.1:5000;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $remote_addr;
+    proxy_set_header X-Forwarded-Proto $scheme;
+}
+```
+
+### GitHub 加速提示「无效输入」
+
+若使用 Nginx 反代后 GitHub 加速异常，请参考 [issue #62](https://github.com/sky22333/hubproxy/issues/62#issuecomment-3219572440) 检查 `proxy_set_header Host` 等配置。

+title: Recommended Architecture
+description: Recommended topology and security requirements for public HubProxy deployments.
+---
+
+For public deployments, a reverse proxy in front of HubProxy is recommended to keep the server secure.
+
+## Recommended Topology
+
+```
+Users → CDN (optional) → Caddy/Nginx (private/local) → HubProxy:5000
+```
+
+| Component | Role |
+|-----------|------|
+| CDN | Optional TLS termination and edge caching |
+| Reverse proxy | TLS, real client IP injection, hide backend port |
+| HubProxy | Docker/GitHub proxy logic |
+
+## Requirements When Using a Reverse Proxy
+
+If you follow the recommended topology above (users → proxy → HubProxy):
+
+1. Reverse proxy must **overwrite** `X-Forwarded-For` / `X-Real-IP` (prevent client IP spoofing — never append client-supplied headers)
+2. **Preferably make port 5000 reachable only by the proxy** (bind `127.0.0.1` or firewall)
+3. Overwrite `X-Forwarded-Host` to prevent Host injection in `.sh` scripts
+
+## Scenario Comparison
+
+| Deployment | Per-user rate limit | IP spoof protection | Rating |
+|------------|--------------------|--------------------|--------|
+| CDN → private proxy → HubProxy | ✅ | ✅ | ⭐⭐⭐ |
+| Docker Caddy + HubProxy | ✅ | ✅ | ⭐⭐⭐ |
+| Local Nginx → HubProxy | ✅ | ✅ | ⭐⭐⭐ |
+| Cloudflare direct to HubProxy | ❌ shared CDN IP | ✅ | ⚠️ |
+| Public `0.0.0.0:5000` | ✅ | ✅ | ⚠️ easily abused |

+

+
+## With Reverse Proxy
+
+Typical Compose layout:

+
+The image has no built-in `HEALTHCHECK`. Verify manually:
+
+```bash
+curl http://127.0.0.1:5000/ready

+
+## Compose Logging (Optional)
+
+When using Compose, `docker-compose.yml` configures:
+
+| Option | Meaning |
+|--------|---------|
+| `max-size=200m` | Max size per log file |
+| `max-file=3` | Keep 3 files (~600MB total) |

+title: Reverse Proxy
+description: Configure Caddy and Nginx to pass the real client IP correctly.
+---
+
+The reverse proxy must **overwrite** the real client IP so HubProxy can rate-limit per user and resist IP spoofing.
+
+## Caddy
+
+### Basic
+
+```txt
+example.com {
+    reverse_proxy 127.0.0.1:5000 {
+        header_up X-Real-IP {remote}
+        header_up X-Forwarded-For {remote}
+        header_up X-Forwarded-Proto {scheme}
+        header_up X-Forwarded-Host {host}
+    }
+}
+```
+
+### Behind Cloudflare
+
+```txt
+example.com {
+    reverse_proxy 127.0.0.1:5000 {
+        header_up X-Forwarded-For {http.request.header.CF-Connecting-IP}
+        header_up X-Real-IP {http.request.header.CF-Connecting-IP}
+        header_up X-Forwarded-Proto https
+        header_up X-Forwarded-Host {host}
+    }
+}
+```
+
+## Nginx
+
+:::caution
+Avoid `proxy_add_x_forwarded_for` — it appends client-supplied `X-Forwarded-For` and can break IP resolution.
+:::
+
+```nginx
+location / {
+    proxy_pass http://127.0.0.1:5000;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $remote_addr;
+    proxy_set_header X-Forwarded-Proto $scheme;
+}
+```
+
+### GitHub acceleration shows "invalid input"
+
+If GitHub acceleration fails behind Nginx, check `proxy_set_header Host` per [issue #62](https://github.com/sky22333/hubproxy/issues/62#issuecomment-3219572440).
+
+## How It Works
+
+HubProxy only trusts forwarding headers when the TCP connection comes from trusted private/local ranges:
+
+- `127.0.0.0/8`
+- `10.0.0.0/8`
+- `172.16.0.0/12`
+- `192.168.0.0/16`

+title: FAQ
+description: Frequently asked questions about deploying and using HubProxy.
+---
+
+<details>
+<summary>How is HubProxy different from free CDN proxies?</summary>
+
+HubProxy is fully self-hosted — you control data and bandwidth without relying on unstable third-party CDNs. Customize rate limits, registry allowlists, and upstream SOCKS5 proxies.
+
+</details>
+
+<details>
+<summary>Is a reverse proxy required for public deployment?</summary>
+
+Strongly recommended. It provides TLS, correct client IP passing, and avoids exposing port 5000. See [Recommended Architecture](/en/deployment/architecture/).
+
+</details>
+
+<details>
+<summary>What's the difference between rate-limit and registry whitelists?</summary>
+
+`[security].whiteList` exempts IPs from rate limiting. `[access].whiteList` controls which Docker images, GitHub repos, and Hugging Face resources can be proxied. They are independent.
+
+</details>
+
+<details>
+<summary>How do I format GitHub acceleration URLs?</summary>
+
+Prefix the **full original URL** with your HubProxy host, e.g. `https://example.com/https://github.com/owner/repo/releases/download/...`. Path-prefix rewrites like `/github/owner/...` are not supported. See [GitHub Acceleration](/en/guides/github-proxy/).
+
+</details>
+
+<details>
+<summary>GitHub acceleration shows 'invalid input'?</summary>
+
+Common causes: wrong URL format (using `/github/` prefix instead of full URL), or incorrect Nginx `Host` header. See [GitHub Acceleration](/en/guides/github-proxy/) and [issue #62](https://github.com/sky22333/hubproxy/issues/62#issuecomment-3219572440).
+
+</details>
+
+<details>
+<summary>How does the offline image API work?</summary>
+
+Two steps: `GET /api/image/download?image=...&mode=prepare` for a token, then download with that token. There is no `/v2/offline/...` path. See [Offline Images](/en/guides/offline-images/).
+
+</details>
+
+<details>
+<summary>All users share one IP behind Cloudflare?</summary>
+
+If HubProxy connects directly to Cloudflare edges, rate limits apply per Cloudflare IP, not per user. Add a private reverse proxy that writes `CF-Connecting-IP` to forwarding headers.
+
+</details>
+
+<details>
+<summary>How do I verify the service is running?</summary>
+
+Visit `https://example.com/ready` — a healthy response includes `ready`, `service`, `version`, and `uptime_sec`. This path **counts toward** the IP rate limit; avoid high-frequency polling.
+
+</details>
+
+<details>
+<summary>Docker logs consuming too much disk?</summary>
+
+`docker run` defaults to ~20MB logs. [Docker Compose](/en/deployment/docker/) preconfigures `200m × 3` rotation; adjust `logging.options` in compose as needed.
+
+</details>
+
+<details>
+<summary>Does HubProxy support resume or multi-part downloads?</summary>
+
+**GitHub / Hugging Face file downloads: yes.** The proxy forwards `Range` headers and passes through upstream 206 responses — `wget -c` and multi-threaded Range downloads work (except `.sh` / `.ps1` script rewriting).
+
+**Docker pulls: no in-layer Range.** Blobs are streamed whole; clients retry failed layers or pull layers in parallel.
+
+**Offline tar API: no** resume. See [Transfer Capabilities](/en/guides/capabilities/).
+
+</details>
+
+<details>
+<summary>How do I add a new acceleration domain?</summary>
+
+Add a regex to `githubExps` in `src/handlers/github.go`. See [Development & Build](/en/guides/development/).
+
+</details>
+
+<details>
+<summary>Why can't I pull private images with authType github?</summary>
+
+`authType` labels auth endpoints only — credential injection is not yet implemented. All registry pulls use anonymous auth and client `Authorization` headers are not forwarded. **Private authenticated images cannot be pulled through HubProxy.**

+After verification, set up a **custom domain + reverse proxy + HTTPS** (Caddy / Nginx) so clients use `https://example.com` instead of bare `http://IP:5000`. See [Recommended Architecture](/en/deployment/architecture/) and [Reverse Proxy](/en/deployment/reverse-proxy/).

+title: Transfer Capabilities
+description: Transfer behavior for Docker pulls and GitHub downloads in HubProxy.
+---
+
+Based on current code in `src/handlers/docker.go` and `src/handlers/github.go`.
+
+## Docker Image Pulls
+
+HubProxy fetches manifests and blobs via go-containerregistry, then returns them over HTTP.
+
+| Capability | Supported | Notes |
+|------------|-----------|-------|
+| Manifest cache | ✅ | GET cached; digest 24h, `latest` etc. 10m |
+| Token cache | ✅ | Upstream `expires_in` driven |
+| Multi-registry paths | ✅ | e.g. `example.com/ghcr.io/owner/image:tag` |
+| containerd `ns` param | ✅ | Matches `[registries]` entries |
+| Auth realm rewrite | ✅ | Upstream token → HubProxy `/token` |
+| HTTP Range / in-layer resume | ❌ | Blobs always fetched fully; client `Range` ignored |
+| Layer-level retry | ✅ | Docker/containerd retries failed layers |
+
+:::note
+Each layer costs at least one blob request against rate limits. No Range inside a layer, but clients may pull **different layers** in parallel.
+:::
+
+## GitHub / Hugging Face Downloads
+
+The GitHub proxy (`proxyGitHubWithRedirect`) forwards **all client request headers** (including `Range`) upstream and passes through **status codes and response headers** (`Content-Range`, `Accept-Ranges`, etc.) before streaming the body.
+
+| Capability | Supported | Notes |
+|------------|-----------|-------|
+| Streaming | ✅ | Direct `io.Copy` for normal files |
+| HTTP Range / resume | ✅ | `wget -c`, `curl -C -`; 206 responses passed through |
+| Multi-connection Range | ✅ | aria2-style parallel chunks (if upstream supports Range) |
+| Redirects | ✅ | Max 20; GitHub Location URLs rewritten |
+| HTML block | ✅ | `text/html` etc. → 403 |
+| File size limit | ✅ | `[server].fileSize`, default 2GB |
+| `.sh` / `.ps1` rewrite | ⚠️ | Full download + rewrite + chunked output; **no** Range resume |
+
+### wget resume example
+
+```bash
+wget -c "https://example.com/https://github.com/owner/repo/releases/download/v1.0.0/large.bin"
+```
+
+See `src/handlers/github.go` lines 113–118 (header forward) and 209–231 (response pass-through).
+
+## Offline image tar
+
+| Capability | Supported |
+|------------|-----------|
+| Streaming tar | ✅ |
+| One-time token (2 min) | ✅ |
+| Range / resume | ❌ |
+| `Cache-Control: no-store` | ✅ |

+title: Registry Sources
+description: Configure upstream registry mappings in HubProxy.
+---
+
+HubProxy uses the `[registries]` section for third-party registry upstreams and auth endpoints. Docker Hub always proxies to `registry-1.docker.io` and is not configured here.
+
+## Default Mappings
+
+`config.toml` includes common registries:
+
+```toml
+[registries."ghcr.io"]
+upstream = "ghcr.io"
+authHost = "ghcr.io/token"
+authType = "github"
+enabled = true
+
+[registries."gcr.io"]
+upstream = "gcr.io"
+authHost = "gcr.io/v2/token"
+authType = "google"
+enabled = true
+
+[registries."quay.io"]
+upstream = "quay.io"
+authHost = "quay.io/v2/auth"
+authType = "quay"
+enabled = true
+
+[registries."registry.k8s.io"]
+upstream = "registry.k8s.io"
+authHost = "registry.k8s.io"
+authType = "anonymous"
+enabled = true
+```
+
+## authType Values
+
+| authType | Meaning |
+|----------|---------|
+| `anonymous` | Anonymous registry (e.g. registry.k8s.io) |
+| `github` | GHCR auth endpoint |
+| `google` | GCR auth endpoint |
+| `quay` | Quay.io auth endpoint |
+
+:::note
+`authType` matches upstream token auth endpoints only. The current version does **not** inject GitHub tokens or Google service accounts — all pulls use anonymous auth and client credentials are not forwarded. **Private authenticated images cannot be pulled.**
+:::
+
+## Pull Path Format
+
+```bash
+# Docker Hub (no registry prefix; library and latest added automatically for official images)
+docker pull example.com/nginx
+
+# Third-party registry
+docker pull example.com/ghcr.io/owner/image:tag
+```
+
+Also supports containerd `ns` query parameter for configured registries.
+
+## Enable/Disable
+
+```toml
+[registries."quay.io"]
+enabled = false
+```
+
+## Token and Manifest Cache
+
+`[tokenCache]` controls upstream auth token and manifest caching:
+
+```toml
+[tokenCache]
+enabled = true
+defaultTTL = "20m"
+```
+
+Digest refs cache for 24 hours; common tags like `latest` cache for 10 minutes. See [config.toml Reference](/en/configuration/reference/#tokencache).

+title: Docker Mirror
+description: Configure Docker clients to pull images through HubProxy.
+---
+
+HubProxy implements Docker Registry API v2 and can accelerate Docker Hub and multiple third-party registries.
+
+## Configure Docker Client
+
+Edit `/etc/docker/daemon.json` (or Docker Desktop settings on Windows):
+
+```json
+{
+  "registry-mirrors": ["https://example.com"]
+}
+```
+
+Restart Docker:
+
+```bash
+sudo systemctl restart docker
+```
+
+## Supported Registries
+
+| Registry | Notes |
+|----------|-------|
+| Docker Hub | Default `registry-1.docker.io`, no path prefix needed |
+| ghcr.io | GitHub Container Registry |
+| gcr.io | Google Container Registry |
+| quay.io | Red Hat Quay |
+| registry.k8s.io | Kubernetes official images |
+
+Extend or disable in `[registries]` — see [Registry Sources](/en/guides/docker-mirror-sources/).
+
+## Pull Examples
+
+```bash
+# Docker Hub official image (no library prefix needed)
+docker pull example.com/nginx
+
+# Docker Hub user image
+docker pull example.com/user/app:tag
+
+# Third-party registry (path includes registry domain)
+docker pull example.com/ghcr.io/owner/image:tag
+```
+
+The `library/` namespace is added automatically for official images, and `latest` is used when no tag is given — `example.com/nginx` is equivalent to `example.com/library/nginx:latest`.
+
+## Image Search
+
+The web UI (`enableFrontend = true`) provides Docker Hub search and tag browsing. API access:
+
+```bash
+curl "https://example.com/api/search?q=nginx"
+curl "https://example.com/api/tags/library/nginx"
+```
+

+title: GitHub Acceleration
+description: Accelerate GitHub Release, Raw, Clone, API, and Hugging Face downloads with HubProxy.
+---
+
+Requests that do not match `/v2`, `/token`, `/api`, or other registered routes are handled by the GitHub proxy. Prefix the **full original URL** with your HubProxy host; if the URL matches a supported pattern, the handler reconstructs it and proxies to GitHub, Hugging Face, or other upstreams — otherwise it returns "invalid input".
+
+## How to Accelerate
+
+Prefix your original URL with the HubProxy host. Two formats are supported.
+
+### Full URL (Recommended)
+
+```bash
+# Release download
+curl -L -O "https://example.com/https://github.com/owner/repo/releases/download/v1.0.0/app.tar.gz"
+
+# Git clone
+git clone https://example.com/https://github.com/owner/repo.git
+
+# API
+curl "https://example.com/https://api.github.com/repos/owner/repo/releases/latest"
+```
+
+### Global Git acceleration
+
+Use `url.<base>.insteadOf` so every `https://github.com/` clone/fetch goes through HubProxy automatically:
+
+```bash
+git config --global url."https://example.com/https://github.com/".insteadOf "https://github.com/"
+```
+
+Then clone as usual:
+
+```bash
+git clone https://github.com/owner/repo.git
+# actually requests https://example.com/https://github.com/owner/repo.git
+```
+
+To remove:
+
+```bash
+git config --global --unset url.https://example.com/https://github.com/.insteadOf
+```
+
+### Omit `https://`
+
+HubProxy auto-prepends the scheme:
+
+```bash
+curl -L -O "https://example.com/github.com/owner/repo/releases/download/v1.0.0/app.tar.gz"
+```
+
+:::caution
+**Not supported:** path-prefix rewrites like `https://example.com/gh/owner/repo/...` or `/raw/owner/...` — these return "invalid input".
+:::
+
+## Supported URL Types
+
+| Type | Path pattern |
+|------|-------------|
+| Release / Archive | `github.com/{owner}/{repo}/releases/...`, `/archive/...` |
+| Raw / Blob | `github.com/{owner}/{repo}/raw/...` (`/blob/` auto-converted to `/raw/`) |
+| Git protocol | `github.com/{owner}/{repo}/info/...`, `/git-...` |
+| Raw domains | `raw.githubusercontent.com/...`, `raw.github.com/...` |
+| API | `api.github.com/repos/{owner}/{repo}/...` |
+| Gist | `gist.github.com/...`, `gist.githubusercontent.com/...` |
+| Hugging Face | `huggingface.co/...`, `cdn-lfs.hf.co/...` |
+| GitHub Assets | `github.githubassets.com/...`, `opengraph.githubassets.com/...` |
+
+## Script Nesting
+
+HubProxy can rewrite GitHub URLs inside `.sh` / `.ps1` install scripts (max 10MB). Behind a reverse proxy, set `X-Forwarded-Host` correctly — see [Reverse Proxy](/en/deployment/reverse-proxy/).
+
+## Limits and Blocks
+
+| Limit | Description |
+|-------|-------------|
+| Web content | `text/html`, `application/xml`, etc. are blocked (403) — not for browsing GitHub pages |
+| File size | `[server].fileSize` caps single-file downloads (default 2GB) |
+| Repo access | `[access].whiteList` / `blackList` restrict proxied GitHub repos and Hugging Face resources |
+
+Large Release files support `wget -c` resume — see [Transfer Capabilities](/en/guides/capabilities/).
+
+```toml
+[server]
+fileSize = 2147483648
+
+[access]
+whiteList = ["trusted-org/*"]
+blackList = ["*/malicious-repo"]
+```

+
+Kubernetes nodes typically pull images via **containerd**, not Docker `daemon.json`.
+
+## K3s
+
+Create `/etc/rancher/k3s/registries.yaml` on each node:
+
+```yaml
+mirrors:
+  docker.io:
+    endpoint:
+      - "https://example.com"

+```
+
+Restart:
+
+```bash
+sudo systemctl restart k3s        # server
+sudo systemctl restart k3s-agent  # agent
+```
+
+Verify with **crictl** (mirrors don't apply to `ctr`):
+
+```bash
+sudo crictl pull docker.io/library/nginx:latest
+```
+
+## RKE2
+
+Use `/etc/rancher/rke2/registries.yaml`, same format. Restart `rke2-server` or `rke2-agent`.
+
+## Native containerd (1.5+)
+
+```bash
+sudo mkdir -p /etc/containerd/certs.d/docker.io

+
+```toml
+server = "https://registry-1.docker.io"

+  capabilities = ["pull", "resolve"]
+```
+
+GHCR: `/etc/containerd/certs.d/ghcr.io/hosts.toml` with `server = "https://ghcr.io"`.

+title: Offline Images
+description: Package Docker images as tar files online, with single and batch download.
+---
+
+HubProxy's web UI (`enableFrontend = true`) and API package images as tar archives without a local Docker daemon.
+
+Downloads use a **two-step flow**: `prepare` for a one-time token, then download with that token. Tokens expire in **2 minutes** and are bound to client IP and User-Agent.
+
+## Web UI
+
+Visit the HubProxy homepage and use the offline image feature. Leave architecture empty to prefer `linux/amd64`; if a specified architecture is unmatched, the first available platform in the multi-arch index is used.
+
+## Image Reference Format
+
+Besides Docker Hub official images, enter a full registry-prefixed reference to pull from other platforms:
+
+| Source | Example input |
+|--------|---------------|
+| Docker Hub | `nginx`, `redis:7` |
+| GHCR | `ghcr.io/sky22333/hubproxy`, `ghcr.io/owner/app:v1.0` |
+| Quay | `quay.io/coreos/etcd:latest` |
+| GCR / K8s | `gcr.io/distroless/base`, `registry.k8s.io/pause:3.9` |
+
+Missing tags default to `:latest`. Single-segment names (no `/`) get the `library/` namespace. The registry must be enabled in `[registries]` and the image must be anonymously pullable.
+
+## Compressed Layers
+
+The web UI and API expose a compressed-layers toggle (`compressed` / `useCompressedLayers`, **on by default**). **Keep it enabled** in most cases.
+
+| Setting | Contents of each `layer.tar` in the archive | Size | Use case |
+|---------|-----------------------------------------------|------|----------|
+| On (default) | **Compressed blob** from the registry (usually gzip) | Smaller, faster download | Modern Docker Engine, `docker load` |
+| Off | **Uncompressed** filesystem layer tar (classic `docker save` format) | Larger, slower to build | Older Docker Engine versions or environments that only accept uncompressed layers |
+
+HubProxy outputs a `docker load`-compatible tar. With compression enabled, each layer keeps the upstream compressed blob instead of decompressing and re-packing on the server, which saves bandwidth and CPU. The off switch remains for **legacy Docker** (image format v1 era and early `docker load` implementations): those expect uncompressed filesystem tars in `layer.tar`, matching `docker save` output — disabling compression produces the same layer format.
+
+## Single Image API
+
+**Step 1: Prepare**
+
+```bash
+curl "https://example.com/api/image/download?image=library/nginx:latest&mode=prepare"
+```
+
+Response:
+
+```json
+{
+  "download_url": "/api/image/download?image=library/nginx%3Alatest&token=..."
+}
+```
+
+**Step 2: Download tar**
+
+```bash
+curl -L -o nginx.tar "https://example.com/api/image/download?image=library/nginx:latest&token=YOUR_TOKEN"
+```
+
+Optional parameters:
+
+| Param | Description |
+|-------|-------------|
+| `platform` | Target platform, e.g. `linux/arm64`; empty prefers `linux/amd64`; if specified but unmatched, uses the first available platform in the index |
+| `tag` | Used when image has no tag, default `latest` |
+| `compressed` | Keep registry-compressed layers in tar, default `true` (recommended — see **Compressed Layers** above) |
+
+## Batch API
+
+**Step 1: Prepare**
+
+```bash
+curl -X POST "https://example.com/api/image/batch?mode=prepare" \
+  -H "Content-Type: application/json" \
+  -d '{"images":["nginx:latest","ghcr.io/sky22333/hubproxy:latest"],"useCompressedLayers":true}'
+```
+
+**Step 2: Download combined tar**
+
+```bash
+curl -L -o batch.tar "https://example.com/api/image/batch?token=YOUR_TOKEN"
+```
+
+## Image Info
+
+```bash
+curl "https://example.com/api/image/info?image=library/nginx:latest"
+```
+
+## Limits
+
+| Config / Rule | Default | Description |
+|--------------|---------|-------------|
+| `[download].maxImages` | `10` | Max images per batch |
+| Prepare debounce (single) | 5s | Repeated prepare returns 429 |
+| Prepare debounce (batch) | 60s | Same for batch |
+| Token TTL | 2 min | Invalid if expired or IP/UA mismatch |
+
+```toml
+[download]
+maxImages = 10
+```
+
+## Notes
+
+- Large images take longer; streamed downloads must restart if interrupted
+- Subject to `[access]` lists and IP rate limiting
+- Frontend static routes (`/`, `/images`, `/search`, `/assets/*`) are not rate-limited; `/ready`, API, and proxy requests all count

+title: IP Trust
+description: How HubProxy identifies real client IPs and prevents spoofing.
+---
+
+HubProxy uses Gin's `ClientIP()` with trusted proxy CIDRs to decide when to trust forwarding headers.
+
+## Trusted Proxy CIDRs
+
+Forwarding headers are only read when the TCP connection originates from:
+
+- `127.0.0.0/8` (loopback)
+- `10.0.0.0/8` (private Class A)
+- `172.16.0.0/12` (private Class B)
+- `192.168.0.0/16` (private Class C)
+
+Direct public connections **never** trust forwarding headers.
+
+## Rate Limit Keys
+
+| Protocol | Key |
+|----------|-----|
+| IPv4 | Full IP address |
+| IPv6 | `/64` prefix |
+
+At most 10,000 IP entries are cached in memory.
+
+## `[security].whiteList` vs IP Protection
+
+`[security].whiteList` is a **rate-limit exemption** list, not an access control list:
+
+- Whitelisted IPs skip `[rateLimit]`
+- Independent from IP spoof protection and `[access]` registry control
+
+## Correct Proxy Headers
+
+The proxy must **overwrite** (not append) client IP:
+
+```nginx
+proxy_set_header X-Real-IP $remote_addr;
+proxy_set_header X-Forwarded-For $remote_addr;
+```
+
+See [Reverse Proxy](/en/deployment/reverse-proxy/).
+
+## Cloudflare
+
+When users reach your proxy via Cloudflare, the reverse proxy should read `CF-Connecting-IP` and write it to forwarding headers.
+
+HubProxy does **not** ship a Cloudflare IP trust list — it relies on the private-side proxy writing the correct IP.

+title: Security Overview
+description: HubProxy security model, risks, and best practices.
+---
+
+HubProxy is an open proxy service — improper deployment creates abuse risk. Follow these practices to reduce exposure.
+
+## Core Mechanisms
+
+| Mechanism | Description |
+|-----------|-------------|
+| IP rate limiting | Per real client IP (IPv6 uses `/64`) |
+| IP allow/deny | `[security]` controls rate-limit exemption and blocking |
+| Repo access control | `[access]` restricts proxied images, GitHub repos, and Hugging Face resources |
+| Trusted proxies | Forward headers trusted only from private/local networks |
+| File size limit | `[server].fileSize` prevents oversized file abuse |
+| Offline download tokens | One-time tokens bound to IP and User-Agent, 2-minute TTL |
+
+## Not Built In
+
+HubProxy has **no** admin login, Basic Auth, API keys, or Prometheus `/metrics`. The web UI is a public SPA — security relies on network placement and configuration.
+
+## Main Risks
+
+1. **Open proxy**: Public `0.0.0.0:5000` without `[access].whiteList` lets anyone use your bandwidth
+2. **IP spoofing**: Reverse proxy that appends instead of overwriting `X-Forwarded-For` bypasses rate limits
+3. **Host injection**: Missing `X-Forwarded-Host` causes incorrect URLs in rewritten `.sh` scripts
+
+## Recommendations
+
+- Use [Recommended Architecture](/en/deployment/architecture/): CDN (optional) → reverse proxy → HubProxy
+- Configure `[access].whiteList` for public services
+- Overwrite `X-Forwarded-For`, `X-Real-IP`, and `X-Forwarded-Host` at the proxy
+- Expose public services through a reverse proxy instead of port 5000 directly
+- Review `[access].blackList` and access logs regularly

+title: 常见问题
+description: HubProxy 部署与使用中的常见问题解答。
+---
+
+<details>
+<summary>HubProxy 和免费 CDN 代理有什么区别？</summary>
+
+HubProxy 是完全自托管的代理服务，数据与带宽由你自己控制，不依赖第三方免费 CDN 的不稳定性。你可以自定义限流、仓库白名单和上游 SOCKS5 代理。
+
+</details>
+
+<details>
+<summary>公网部署必须配置反向代理吗？</summary>
+
+强烈建议。反代提供 TLS 终止、正确传递客户端 IP，并避免将 5000 端口直接暴露。详见 [推荐部署架构](/deployment/architecture/)。
+
+</details>
+
+<details>
+<summary>限流白名单和仓库白名单有什么区别？</summary>
+
+`[security].whiteList` 是限流豁免 IP，不影响可代理的仓库。`[access].whiteList` 控制允许代理哪些 Docker 镜像、GitHub 仓库与 Hugging Face 资源。两者独立配置。
+
+</details>
+
+<details>
+<summary>GitHub 加速链接怎么写？</summary>
+
+在**完整原始 URL** 前加上 HubProxy 域名，例如 `https://example.com/https://github.com/owner/repo/releases/download/...`。不支持 `/github/owner/...` 路径替换写法。详见 [GitHub 加速](/guides/github-proxy/)。
+
+</details>
+
+<details>
+<summary>GitHub 加速提示「无效输入」？</summary>
+
+常见原因：URL 格式错误（使用了 `/github/` 前缀而非完整 URL），或 Nginx 反代未正确设置 `Host` 头。参考 [GitHub 加速](/guides/github-proxy/) 与 [issue #62](https://github.com/sky22333/hubproxy/issues/62#issuecomment-3219572440)。
+
+</details>
+
+<details>
+<summary>离线镜像 API 怎么用？</summary>
+
+需两步：先 `GET /api/image/download?image=...&mode=prepare` 获取 token，再携带 token 下载。不存在 `/v2/offline/...` 路径。详见 [离线镜像包](/guides/offline-images/)。
+
+</details>
+
+<details>
+<summary>使用 Cloudflare 后所有用户共用一个 IP 怎么办？</summary>
+
+若 HubProxy 直连 Cloudflare 边缘节点，限流会按 Cloudflare IP 计数，无法区分用户。正确做法是在 Cloudflare 后面加一层私网反代，由反代写入 `CF-Connecting-IP`。
+
+</details>
+
+<details>
+<summary>如何验证服务是否正常？</summary>
+
+访问 `https://example.com/ready`，正常时返回 `{"ready":true,"service":"hubproxy",...}`，包含 `version` 与 `uptime_sec` 字段。该路径**会计入** IP 限流，避免高频轮询。
+
+</details>
+
+<details>
+<summary>Docker 日志占用磁盘过大？</summary>
+
+`docker run` 默认日志约 20MB。若使用 [Docker Compose](/deployment/docker/)，已在 compose 文件中配置 `200m × 3` 日志轮转；也可自行在 compose 中调整 `logging.options`。
+
+</details>
+
+<details>
+<summary>支持断点续传或多线程分片下载吗？</summary>
+
+**GitHub / Hugging Face 文件下载：支持。** 代理会透传 `Range` 请求头并将上游 206 响应原样返回，`wget -c`、多线程 Range 分片均可使用（`.sh` / `.ps1` 脚本改写除外）。
+
+**Docker 镜像拉取：不支持 layer 内 Range。** blob 整层转发，但客户端可重试失败 layer 或并行拉取不同 layer。
+
+**离线 tar API：不支持**断点续传。详见 [传输特性](/guides/capabilities/)。
+
+</details>
+
+<details>
+<summary>如何添加新的加速域名？</summary>
+
+在 `src/handlers/github.go` 的 `githubExps` 数组中添加正则表达式，详见 [二次开发与构建](/guides/development/)。
+
+</details>
+
+<details>
+<summary>authType 配置了 GitHub Token 为什么私有镜像仍拉不下来？</summary>
+
+当前版本 `authType` 仅标识认证端点类型，尚未实现凭据注入，所有 Registry 均使用匿名拉取，且不转发客户端 `Authorization` 头。**无法**通过 HubProxy 拉取需要认证的私有镜像。

+description: HubProxy 在 Docker 拉取与 GitHub 下载场景下的能力边界说明。
+---
+
+本文基于当前代码实现（`src/handlers/docker.go`、`src/handlers/github.go`），说明各场景的传输行为。
+
+## Docker 镜像拉取
+
+HubProxy 通过 go-containerregistry 向上游拉取 manifest 与 blob，再以 HTTP 响应形式返回客户端。
+
+| 能力 | 支持 | 说明 |
+|------|------|------|
+| Manifest 缓存 | ✅ | GET manifest 可缓存；digest 24h，`latest` 等 10 分钟 |
+| Token 缓存 | ✅ | 上游 `expires_in` 驱动 |
+| 多 Registry 路径 | ✅ | 如 `example.com/ghcr.io/owner/image:tag` |
+| containerd `ns` 参数 | ✅ | 识别 `[registries]` 中的 registry |
+| 认证 realm 改写 | ✅ | 上游 token 地址改写到 HubProxy `/token` |
+| HTTP Range / layer 内续传 | ❌ | blob 始终整层读取后转发，不读取客户端 `Range` |
+| layer 级重试 | ✅ | Docker/containerd 拉取失败会重试整个 layer |
+
+:::note
+每个 layer 对应至少一次 blob 请求，均计入 IP 限流。HubProxy 对 blob **不做** Range 分片，但客户端可并行拉取**不同 layer**（多连接）。
+:::
+
+### 与标准 Registry 的差异
+
+- blob 非透明透传，由 HubProxy 从上游完整拉取后再 `io.Copy` 转发
+- 不支持 PATCH/PUT 上传（仅拉取）
+- HEAD / GET manifest 支持
+
+## GitHub / Hugging Face 下载
+
+GitHub 代理（`proxyGitHubWithRedirect`）会将客户端**全部请求头**（含 `Range`）转发上游，并将上游**状态码与响应头**（含 `Content-Range`、`Accept-Ranges`）原样返回，再流式转发 body。
+
+| 能力 | 支持 | 说明 |
+|------|------|------|
+| 流式转发 | ✅ | 普通文件直接 `io.Copy` |
+| HTTP Range / 断点续传 | ✅ | `wget -c`、`curl -C -` 可用；上游返回 206 时原样透传 |
+| 多连接 Range 分片 | ✅ | aria2 等多线程分片下载可用（依赖上游支持 Range） |
+| 重定向跟随 | ✅ | 最多 20 次；GitHub URL 的 Location 自动改写 |
+| 网页类型拦截 | ✅ | `text/html` 等返回 403 |
+| 文件大小限制 | ✅ | `[server].fileSize`，默认 2GB（按响应头 `Content-Length` 校验） |
+| `.sh` / `.ps1` 脚本改写 | ⚠️ | 脚本会完整下载并改写内容后 chunked 输出，**不支持** Range 续传 |
+
+### wget 断点续传示例
+
+```bash
+# 首次下载（中断后可续传）
+wget -c "https://example.com/https://github.com/owner/repo/releases/download/v1.0.0/large.bin"
+```
+
+实现位置：`src/handlers/github.go` 第 113–118 行（转发请求头）、第 209–231 行（透传响应）。
+
+## 离线镜像 tar
+
+| 能力 | 支持 |
+|------|------|
+| 流式打包 tar | ✅ |
+| 一次性 token（2 分钟） | ✅ |
+| Range / 断点续传 | ❌ |
+| `Cache-Control: no-store` | ✅ |

+---
+
+HubProxy 通过 `[registries]` 段配置第三方 Registry 的上游地址与认证端点。Docker Hub 固定代理到 `registry-1.docker.io`，无需在此段配置。
+
+## 默认 Registry 映射
+
+`config.toml` 中预置了常用 Registry：
+
+```toml
+[registries."ghcr.io"]
+upstream = "ghcr.io"
+authHost = "ghcr.io/token"
+authType = "github"
+enabled = true
+

+
+[registries."registry.k8s.io"]
+upstream = "registry.k8s.io"
+authHost = "registry.k8s.io"
+authType = "anonymous"
+enabled = true
+```
+
+## authType 说明
+
+| authType | 含义 |
+|----------|------|
+| `anonymous` | 匿名 Registry（如 registry.k8s.io） |
+| `github` | GHCR 认证端点 |
+| `google` | GCR 认证端点 |
+| `quay` | Quay.io 认证端点 |
+
+:::note
+`authType` 用于匹配上游 token 认证地址，当前版本**不会**据此注入 GitHub Token 或 Google 服务账号。所有 Registry 拉取均使用匿名认证，且不转发客户端凭据，**无法**拉取需要认证的私有镜像。
+:::
+
+## 拉取路径格式
+
+```bash
+# Docker Hub（无需前缀 registry 域名，官方镜像自动补齐 library 与 latest）
+docker pull example.com/nginx
+
+# 第三方 Registry
+docker pull example.com/ghcr.io/owner/image:tag
+```
+
+也支持 containerd 的 `ns` 查询参数识别已配置的 Registry。
+
+## 启用/禁用 Registry
+
+```toml
+[registries."quay.io"]
+enabled = false

+
+## Token 与 Manifest 缓存
+
+`[tokenCache]` 段控制上游认证 Token 与 Manifest 缓存：
+
+```toml
+[tokenCache]
+enabled = true
+defaultTTL = "20m"
+```
+
+digest 引用缓存 24 小时，`latest` 等常用 tag 缓存 10 分钟，详见 [config.toml 参考](/configuration/reference/#tokencache)。

+title: Docker 镜像加速
+description: 配置 Docker 客户端使用 HubProxy 加速镜像拉取。
+---
+
+HubProxy 兼容 Docker Registry API v2，可作为 Docker Hub 及多种第三方 Registry 的镜像加速入口。
+
+## 配置 Docker 客户端
+
+编辑 `/etc/docker/daemon.json`（Windows 为 Docker Desktop 设置）：
+
+```json
+{
+  "registry-mirrors": ["https://example.com"]
+}
+```
+
+重启 Docker：
+
+```bash
+sudo systemctl restart docker
+```
+
+## 支持的 Registry
+
+| Registry | 说明 |
+|----------|------|
+| Docker Hub | 默认 `registry-1.docker.io`，无需路径前缀 |
+| ghcr.io | GitHub Container Registry |
+| gcr.io | Google Container Registry |
+| quay.io | Red Hat Quay |
+| registry.k8s.io | Kubernetes 官方镜像 |
+
+可在 `config.toml` 的 `[registries]` 中扩展或禁用，详见 [Docker 镜像源配置](/guides/docker-mirror-sources/)。
+
+## 拉取示例
+
+```bash
+# Docker Hub 官方镜像（无需写 library 前缀）
+docker pull example.com/nginx
+
+# Docker Hub 用户镜像
+docker pull example.com/user/app:tag
+
+# 第三方 Registry（路径含 registry 域名）
+docker pull example.com/ghcr.io/owner/image:tag
+```
+
+官方镜像会自动补齐 `library/` 命名空间，未指定标签时自动使用 `latest`，即 `example.com/nginx` 等价于 `example.com/library/nginx:latest`。
+
+## 镜像搜索
+
+Web 界面（`enableFrontend = true`）提供 Docker Hub 搜索与标签浏览，也可直接调用 API：
+
+```bash
+curl "https://example.com/api/search?q=nginx"
+curl "https://example.com/api/tags/library/nginx"
+```
+
+## 注意事项
+
+- 拉取一个镜像会请求多个 layer，每个 HTTP 请求均计入 IP 限流配额
+- 公网服务建议配置 `[access].whiteList` 限制可代理的镜像
+- 配合反向代理时确保正确传递客户端 IP，详见 [反向代理配置](/deployment/reverse-proxy/)

+
+HubProxy 兼容 OCI/Distribution Registry API v2。Kubernetes 节点通常由 **containerd** 拉取镜像，配置方式与 Docker `daemon.json` 不同。
+
+## K3s
+
+在每个节点创建 `/etc/rancher/k3s/registries.yaml`：
+
+```yaml
+mirrors:
+  docker.io:
+    endpoint:
+      - "https://example.com"
+  "ghcr.io":
+    endpoint:

+```
+
+重启服务：
+
+```bash
+sudo systemctl restart k3s        # server
+sudo systemctl restart k3s-agent  # agent
+```
+
+验证（使用 **crictl**，mirror 不对 `ctr` 生效）：
+
+```bash
+sudo crictl pull docker.io/library/nginx:latest
+```
+
+## RKE2
+
+配置 `/etc/rancher/rke2/registries.yaml`，格式同上，重启 `rke2-server` 或 `rke2-agent`。
+
+## 原生 containerd（1.5+）
+
+```bash
+sudo mkdir -p /etc/containerd/certs.d/docker.io
+```
+
+`/etc/containerd/certs.d/docker.io/hosts.toml`：
+
+```toml
+server = "https://registry-1.docker.io"
+
+[host."https://example.com"]
+  capabilities = ["pull", "resolve"]
+```
+
+GHCR 示例：`/etc/containerd/certs.d/ghcr.io/hosts.toml`：
+
+```toml
+server = "https://ghcr.io"
+
+[host."https://example.com"]
+  capabilities = ["pull", "resolve"]
+```
+
+确保 `/etc/containerd/config.toml` 启用：
+
+```toml
+[plugins."io.containerd.grpc.v1.cri".registry]
+  config_path = "/etc/containerd/certs.d"
+```

+NAS 上的 Docker 通过图形界面管理，**不要**随意用脚本覆盖整个 `daemon.json`，以免丢失 `data-root` 导致容器丢失。
+
+以下假设 HubProxy 已通过反代暴露在 `https://example.com`。
+
+## 群晖 DSM（Container Manager）
+
+DSM 7.2+ 将「Docker」更名为 **Container Manager**。

+
+## 飞牛 fnOS
+
+官方建议：**不要**用脚本直接改写 `/etc/docker/daemon.json`（含 `data-root`，误删会导致镜像/容器丢失）。
+
+### Web 界面（推荐）
+
+1. **Docker** → **镜像仓库** → **仓库设置** / **加速源设置**
+2. **添加 URL**：`https://example.com`
+3. 拖到列表**顶部**，保存并**重启 Docker**
+
+### 手动编辑（高级）
+
+先备份，仅向 `registry-mirrors` 追加地址，保留 `data-root` 等字段，然后重启 Docker。

+title: 离线镜像包
+description: 在线打包 Docker 镜像为 tar 文件，支持单镜像与批量下载。
+---
+
+HubProxy Web 界面（`enableFrontend = true`）与 API 支持将镜像在线打包为 tar 离线包，无需本地 Docker 环境。
+
+下载采用**两步流程**：先 `prepare` 获取一次性 token，再携带 token 下载。Token 有效期 **2 分钟**，绑定客户端 IP 与 User-Agent。
+
+## Web 界面
+
+访问 HubProxy 首页，在「离线镜像」功能中输入镜像名与标签即可下载。架构选择留空时优先使用 `linux/amd64`；指定架构但匹配不到时，使用多架构索引中的第一个可用平台。
+
+## 镜像名称格式
+
+除 Docker Hub 官方镜像外，可直接输入带 Registry 域名的完整引用，从对应平台拉取并打包：
+
+| 来源 | 输入示例 |
+|------|---------|
+| Docker Hub | `nginx`、`redis:7` |
+| GHCR | `ghcr.io/sky22333/hubproxy`、`ghcr.io/owner/app:v1.0` |
+| Quay | `quay.io/coreos/etcd:latest` |
+| GCR / K8s | `gcr.io/distroless/base`、`registry.k8s.io/pause:3.9` |
+
+未写 tag 时自动补 `:latest`；官方镜像（不含 `/` 的单段名称）会自动补齐 `library/` 命名空间。Registry 需在 `[registries]` 中启用，且镜像可匿名拉取。
+
+## 压缩层
+
+Web 界面与 API 均提供「压缩层」开关（`compressed` / `useCompressedLayers`，**默认开启**）。**建议保持开启**。
+
+| 开关 | tar 内 `layer.tar` 内容 | 体积 | 适用场景 |
+|------|--------------------------|------|---------|
+| 开启（默认） | Registry 中的**压缩 blob**（通常为 gzip） | 更小，下载更快 | 现代 Docker Engine，`docker load` 导入 |
+| 关闭 | **解压后**的文件系统层 tar（与 `docker save` 经典格式一致） | 更大，打包更慢 | 较旧版本 Docker Engine 或仅支持未压缩 layer 的环境 |
+
+HubProxy 输出的 tar 为 `docker load` 兼容格式。开启压缩层时，每层保留上游 Registry 原样压缩数据，避免 HubProxy 在服务端解压再重打包，显著减少传输体积与 CPU 开销。保留关闭选项，是为了兼容**旧版 Docker**（镜像 v1 时代及更早的 `docker load` 实现）：彼时 `layer.tar` 通常为未压缩的文件系统 tar，与 `docker save` 导出结果一致；关闭后输出的 layer 格式与之相同。
+
+## 单镜像 API
+
+**第一步：申请下载**
+
+```bash
+curl "https://example.com/api/image/download?image=library/nginx:latest&mode=prepare"
+```
+
+响应示例：
+
+```json
+{
+  "download_url": "/api/image/download?image=library/nginx%3Alatest&token=..."
+}
+```
+
+**第二步：下载 tar**
+
+```bash
+curl -L -o nginx.tar "https://example.com/api/image/download?image=library/nginx:latest&token=YOUR_TOKEN"
+```
+
+可选参数：
+
+| 参数 | 说明 |
+|------|------|
+| `platform` | 指定平台，如 `linux/arm64`；留空时优先 `linux/amd64`；指定但匹配不到时使用索引中第一个可用平台 |
+| `tag` | 镜像未含 tag 时使用，默认 `latest` |
+| `compressed` | 是否保留 Registry 压缩层写入 tar，默认 `true`（建议开启，见上文「压缩层」） |
+
+## 批量 API
+
+**第一步：申请批量下载**
+
+```bash
+curl -X POST "https://example.com/api/image/batch?mode=prepare" \
+  -H "Content-Type: application/json" \
+  -d '{"images":["nginx:latest","ghcr.io/sky22333/hubproxy:latest"],"useCompressedLayers":true}'
+```
+
+**第二步：下载合并 tar**
+
+```bash
+curl -L -o batch.tar "https://example.com/api/image/batch?token=YOUR_TOKEN"
+```
+
+## 镜像信息
+
+```bash
+curl "https://example.com/api/image/info?image=library/nginx:latest"
+```
+
+## 限制
+
+| 配置 / 规则 | 默认值 | 说明 |
+|------------|--------|------|
+| `[download].maxImages` | `10` | 单次批量镜像数量上限 |
+| prepare 防抖（单镜像） | 5 秒 | 同一用户重复 prepare 会返回 429 |
+| prepare 防抖（批量） | 60 秒 | 同上 |
+| Token TTL | 2 分钟 | 过期或 IP/UA 不匹配则无效 |
+
+```toml
+[download]
+maxImages = 10
+```
+
+## 注意事项
+
+- 大镜像打包耗时较长，流式传输中断后需重新请求
+- 受 `[access]` 黑白名单与 IP 限流约束
+- 前端静态页面（`/`、`/images`、`/search`、`/assets/*`）不计入限流；`/ready`、API 与代理请求均会计入

+title: IP 信任机制
+description: HubProxy 如何识别真实客户端 IP 并防止伪造。
+---
+
+HubProxy 使用 Gin 的 `ClientIP()` 获取客户端地址，并配合可信代理网段判断何时信任转发头。
+
+## 可信代理网段
+
+仅当 TCP 连接来自以下网段时，才读取 `X-Forwarded-For` / `X-Real-IP`：
+
+- `127.0.0.0/8`（本机）
+- `10.0.0.0/8`（私网 A 类）
+- `172.16.0.0/12`（私网 B 类）
+- `192.168.0.0/16`（私网 C 类）
+
+直连公网 IP 的请求**不会**信任任何转发头，直接使用 TCP 远端地址。
+
+## 限流 IP 计算
+
+| 协议 | 限流键 |
+|------|--------|
+| IPv4 | 完整 IP 地址 |
+| IPv6 | `/64` 网段 |
+
+内存中最多缓存 10000 条 IP 记录，不会无限增长。
+
+## `[security].whiteList` 与 IP 防护
+
+`[security].whiteList` 是**限流豁免名单**，不是「允许访问的 IP 列表」：
+
+- 白名单 IP 不受 `[rateLimit]` 限制
+- 与 IP 伪造防护、仓库访问控制（`[access]`）是独立机制
+
+## 正确反代示例
+
+反代必须**覆盖写**（非 append）客户端 IP：
+
+```nginx
+proxy_set_header X-Real-IP $remote_addr;
+proxy_set_header X-Forwarded-For $remote_addr;
+```
+
+详见 [反向代理配置](/deployment/reverse-proxy/)。
+
+## Cloudflare 场景
+
+若用户经 Cloudflare 到达反代，反代应从 `CF-Connecting-IP` 读取真实 IP 并写入转发头，而不是让 HubProxy 直连 Cloudflare。
+
+HubProxy **不**内置 Cloudflare IP 信任列表，依赖「反代在私网侧正确写入 IP」这一架构。

+title: 安全概述
+description: HubProxy 安全模型、风险点与最佳实践。
+---
+
+HubProxy 作为开放代理服务，部署不当可能带来滥用风险。遵循以下实践可显著降低暴露面。
+
+## 核心安全机制
+
+| 机制 | 说明 |
+|------|------|
+| IP 限流 | 按真实客户端 IP 限制请求频率（IPv6 按 `/64`） |
+| IP 黑白名单 | `[security]` 控制限流豁免与封禁 |
+| 仓库访问控制 | `[access]` 限制可代理的镜像、GitHub 仓库与 Hugging Face 资源 |
+| 可信代理 | 仅信任来自私网/本机的转发头，防止 IP 伪造 |
+| 文件大小限制 | `[server].fileSize` 防止超大文件滥用 |
+| 离线下载 Token | 一次性 token，绑定 IP 与 User-Agent，2 分钟过期 |
+
+## 未内置的能力
+
+HubProxy **没有**管理后台登录、Basic Auth、API Key 或 Prometheus 指标端点。Web 界面为公开 SPA，安全依赖网络层与配置策略。
+
+## 主要风险
+
+1. **开放代理**：公网直连 `0.0.0.0:5000` 且无 `[access].whiteList` 时，任何人可使用你的带宽代理任意仓库
+2. **IP 伪造**：反代未覆盖写 `X-Forwarded-For` 时，攻击者可绕过限流
+3. **Host 注入**：反代未设置 `X-Forwarded-Host` 时，`.sh` 脚本可能生成错误加速 URL
+
+## 推荐实践
+
+- 使用 [推荐部署架构](/deployment/architecture/)：CDN（可选）→ 反代 → HubProxy
+- 公网服务配置 `[access].whiteList`
+- 反代覆盖写 `X-Forwarded-For`、`X-Real-IP`、`X-Forwarded-Host`
+- 公网服务建议通过反代暴露，不直接开放 `5000` 端口
+- 定期审查 `[access].blackList` 与访问日志
